Application filed April 29, 1918. Serial 1i o. 231,510.

To all whom t may concern:

Be it known that 1, WILLIAM B. SULLrvAN, a citizen of the United States,residing in the city of St. Louis and State of Missouri, have inventedcertain new and useful llmprovements in Removable Saw-Handles, of whichthe following is a specilcation.

My inventionrelates to improvements in removable saw-handles andpractical fastening means therefor, for conveniently and securelypositioning and locking the handle to the end of a saw-blade and yetpermit ready and quick removal of the handle from the saw-blade when itis desired to place the same yin a Htool-box, thereby substantiallyshortening the saw-proper and enable it to be packed in a tool-boxshorterin length than would be required for the saw were the handle notremovable.

A further object of the invention is to provide a removable saw handleand fastening 1 means ltherefor which is a distinct and practicalimprovement in saw artA to overcome certain important practicalobjections to, and defects in the usual means of afixing handles to sawblades.

l attain these and similar objects by the construction, arrangement andcombination of parts more fully described in the follow-l ingspecification and finally pointed out in the claim hereto appended.

Referring to the accompanying drawings forming a part of thisspecification wherein like characters of reference denote similar partsthroughout the several views:

Figure 1, is a side elevation of a sawblade, `removable-handle andfastening means therefor constructed in accordance with my invention,the handle being shown detached in full lines and partially removed indotted lines.

Fig. 2, is a side elevation of a saw-blade showin the fasteningreceiving slots formed in one end thereof.

Fig. 3, is a detail taken on line X-X of Fig. 1. l

Fig. 4:, is a longitudinal sectional view of the fastening means carriedby the handle.

Fig. 5, is a detail, in section, of one of the female fastening members.

Fig. 6, is a detail in side elevation of the male fastening member.

Fig. 7, is a bottom plan view of the sawhandle, blade and the springlocking means.

Referring to the drawings the reference character 1 designates anordinary standard.

saw-blade while 2 designates the usual sawtion .3.

The saw-blade 1 is provided at one end wlth a slotted opening 4 havingan upper open end communicating with the upper edge of the saw-bladenear the upper corner @thereof r1)lie saw-blade 1 is further providedwith the slotted opening 6 having an outer open end communicating withthe beveled edge 7. rlhe slotted opening 6 is positioned below and tooneside of the slotted opening i. The saw-blade 1 is still further providedwith a third slotted opening 8 having an outer open end communicatingwith the beveled edge 7. rllhe slotted opening 6 is provided with thecurved upper edge 9 which 1s the arc of a circle using point 10 of sloti, as a center. Ilihe slotted opening 8 is provided With the curvedupper edge' l1 which is the arc of a circle using point 10 of slot d,

l as a center.

rFhe saw blade 1 'is still further provided with a downwardly andinwardly extending slotted opening 12 having its outer end communicatingwith. the beveled edge 7 ofthe saw-blade. 'llhe upper edge of theslotted opening is suitably curved, as at 13, the reason being apparenthereinafter. end of the slotted opening l2 terminates in an upwardlyextending slot 1i thereby providing a locking-lip l5- at the lower endof the curved edge 13, as clearly shown in Fig. 2. The slotted opening12, it will be observed is in turn positioned below the slotted opening8.

The saw-blade handle 2 is provided with the usual blade receiving slot16, as shown in Figs. 3 and i.

The saw-blade handle 2 is further provided with three interlockingfasteners, as

shown in Fig. 1, one for each slotted opening The inner A of a shankportion 21 having a diameter l flanged head 23 on the opposite end. Thehead 23 is provided with a screw-driver le eeiving slot 24e formed inits outer face.

l/Vhen the two fastenei inemloeis are intel? 1 slot i6 and extendingcleat thioiigh the handle. ,elften these hollovwstem membeis have beenpositioned the stem 22 is seifeved into position in the hollow-stemmmnbei ae cleanly sho-wn in 3 and l.

lt will be observed that the intenloclilng7 tastenevs are eachpositioned that the top Jtastener cani-ied in openingz isj in placing ahandle upon ablade, liest inseted into the slotted opening 1l, to act asa pivot on hinge. lifter this operation the handle is forced home, asshown in full lines i'oni the position shown in dotted lines in l7causing the i'emaining two tastenei's to ent-ev their respective slots 6and 8. When the handle is being linally forced home oi into its normalposition itvill be obsenved that the end 28 of a spring-ketenen onlocking catch' 29 strikes the cmived edge i3 and i'inally the lip l5passes through the slotted opening 30 of the keeper and is engaged bythe cross-piece 3l which holds and locks the saw-handle liimly in itsassembled position as shown in full lines in le o iremove the handle allthe opeiatonv does is to release the spring lteepeiv Enom engagementwith the lip l5 ol the saw-blade and pull out and up on the saw handleon in other Words, gives the handle an upward turning movement using thelippen intel'- locking' fastener as a pivot or hinge., Alfter the twolower fasteners have been removed tem the receiving slots 6 and 8,respetively, the handle can be lifted olif so as to -remove the appelfastener :from its veeeiv- `ing: slot 4 f lt will thus be seen that thesaw-handle @an be easily and quickly alined to the saw- Ibladel oiremoved therefrom and placed :teo
